Connect the two with a single master link and measure how long you need the chain to be from the engine sprocket to the rear sprocket. Doing so requires you to connect at least two chains, and to do so you remove the master links from both chains to lay the chains out. The 415 chains that come with most engine kits are sized for standard frames, so stretched frames require much longer chain. The size of your drive chain is integral for the engine’s functionality. Chopper frames are usually stretched, so there are two components that need to be extended in order for the engine to function properly: the chain and the cables. However, gas engine kits these days are made for standard 26” beach cruiser frames which are pretty compact. These mounts bolt around the hub and give around ¾” of clearance from the wheel.Ĭhoppers look so great because they have a stretched look to them. In this case, something like the Manic Mechanic Sprocket and Adapter assembly will be perfect for this application. There are wider wheels on the market that require more than ½” of room from the wheel to avoid chain rubbing. Such mounts are great for OCC chopper bikes, as these only require about ½” of room from the wheel to clear the wheel. The sprocket is then mounted on the adapter and sets the sprocket far enough away from the wheel to clear the tire. This particular style of mount requires the installer to drill into the hub of the wheel and bolt the adapter to the hub. One solution is a mount that consists of a circular adapter (around ½” thick) which has ports drilled into it. There are a couple of methods on the market to set the sprocket out further than gaskets will. Moreover, the chain will rub against the rear tire, leading to damage to the tire and possibly the chain. Without special sprocket mounts, the engine sprocket will not align with the rear sprocket and the chain will be crooked.
